Origin Motion

The origin is the center of the Whorld image. It's the point from which the rings emanate, or in Reverse, the point towards which they converge. The origin can move, and the types of motion are as follows:

None

The origin stays put.

Drag

The origin follows the mouse.

Random

The origin jumps to random locations.

In Random mode, the jumps occurs at evenly spaced intervals, and the time between jumps is determined by the tempo. The tempo can be entered manually, via the Master dialog's tempo slider, or by tapping the Tab key along with the beat (see tap tempo). The tempo can also be synchronized to MIDI clocks.

Origin motion can be enabled via Image/Origin or the toolbar, using the commands listed below. In Veejay mode, F1 toggles between drag and random.

Center

Shift+C

Stops the origin and centers it within the window.

Drag

Shift+D

Enables drag, or if it's already enabled, disables it.

Random

Shift+R

Enables random, or if it's already enabled, disables it.

Origin motion is affected by damping. Damping controls how precisely the origin tracks new positions, whether drag-generated or random. When damping is zero, the origin tracks precisely. As damping increases, the origin lags behind new positions, and catches up gradually, slowing down as it gets closer.

Origin motion is also affected by trail. Trail determines whether the rings stay together, or spread themselves out. When trail is zero, the rings stay together; as trail increases, rings further from the origin lag behind, creating a slinky effect. When trail is at maximum, rings don't move from their birth positions.
